| 摘 要： | 通过对不同工况下氯化十六烷基三甲基季铵盐(CTAC)减阻流体在二维流道中减阻性能的测定,分析了温度、质量分数、配比变化对流体减阻性能的影响,应用激光相位多普勒测速仪测量了流体的速度场,对流体的湍流特征进行试验研究,结果表明,即使对同种减阻方式,CTAC减阻流体的减阻也存在极限和优选,减阻流体的横向和轴向速度脉动及雷诺应力均远小于牛顿流体。

| Abstract: | Drag reducing performances of Cetyltrimethyl Ammonium Chloride (CTAC) drag reducing fluid in two-dimensional channel under different experimental situations were measured. The results indicate that there are the maximum limitation and optimum option even for the same drag reducing additive. Phase Doppler Anemometry (PDA) was applied to measuring the turbulent characteristics of drag reducing fluid. By contrast with those of Newtonian fluid, it is found that the velocity fluctuations and the Reynolds shear stresses in the drag reducing fluid decrease dramatically. |
